There have been organisms from the beginning of time that have had hard parts on their body. This is described in creationism.
Hard body parts that support your body include bones, which provide structure and support, and teeth, which help with chewing and breaking down food. Additionally, hard body parts such as the skull protect vital organs like the brain and provide support for the head and neck.
The base of the microscope supports the entire instrument and provides stability. Additionally, the arm holds the upper parts of the microscope, such as the stage and eyepiece, in place. Both the base and arm work together to support the entire body of the microscope.
Most organisms during the Precambrian time did not have hard body parts. They were mostly soft-bodied and lacked the mineralized structures seen in later periods.
